1. The document proposes the Digital Instrument Appropriation Model (DIAM) to describe the appropriation process of digital artifacts over time through their evolution. 2. DIAM extends instrumental theory by conceptualizing digital artifacts as dynamic instruments that change with user particularization and circulations between users. 3. A case study applying DIAM to analyze researchers' appropriation of a video annotation tool found it helped explain how users particularized information structures, though it failed to fully capture collaborative dimensions and tool combinations.

6. A MODEL FOR APPROPRATION:
REQUIREMENTS
• Account for the richness of appropriation
process
• Variety of related processes
• Situated into a social / cultural / technological
context
• Explain specifics of digital technology
appropriation
• Gap between user and digital representations
• Structures and operations to bridge this gap

26. CASE STUDY: PRESENTATION
• Context
• 7 Cinema Researchers
• New Video Annotation Tool
• Collaborative Movie Analysis Practice
• Research Question
• To what extent does DIAM help to describe
appropriation?
• Material
• Pre & Post Interviews (14)
• On field-observations
• Interaction traces & Screenshots

29. CASE STUDY : CONCLUSION
The model helps to describe appropriation
• Explain user particularization of information
structures
The model fails into taking into account
• Instrument based on multiple-tool
• Collaborative dimension of appropriation
Potential of interaction traces
• Detect circulation and moment of instrumental
instability
• Detect utilization schemes
29

30. CONCLUSIONS
• A dynamic model to describe evolutions of
digital artifact over the appropriation process
• Extending Instrumental Theory
• Taking into account specifics about appropriation of
digital artifacts
• First experimentation promising
• Key concepts to design and evaluate
appropriability of artifacts
30

31. PERSPECTIVES
Fine-grained modelling of interaction level
Understand the role of mediation over users’
representation of data
Overstepping the « 1 Instrument = 1 Application »
simplification
Towards appropriation-aware technology ?
• From interaction traces to appropriation traces
• Better understanding of usage evolution over time
• Assist user with instrumental development
